I'm not sure I agree, as the proposal appears to impair the user
experience by adding a new level of complexity: The user then has to
remember which options come before the subcommand and which options come
after. That's why the man pages have maintained a diplomatic silence
about this possibility of specifying metaoptions before the subcommand
and should continue to do so.
